ANITED STATES HARRY D. SPANGLER, OF RUSHVILLE, INDIANA, ASSIGN OR TONORRIS & BROTHER, OF SAME PLACE.

SEEDlNG-MACHINE.

EEPECIPICATION forming part of Letters Patent No. 304,368, datedSeptember 2, 1884.

Application filed January 17, 1884. (No model.)

To aZZ whom it may concern Be it known that I, HARRY D. SPANGLER, ofRushville, Rush county, Indiana, have invented certain new and usefulImprovements in Seeding-Machines, of which the following isaspecification.

This invention pertains to that classof seeding-machines in which thedelivery is of fected through the medium of a moving plate or diskprovided wit-h seed-carrying cells which are brought one by one over asuitable discharge-point.

The invention relates particularly to the construction of the knockeror-presser which discharges from the seed-cells such grains as areindisposed to drop from the cells oft-heir own accord at the properpoint.

The nature of the invention will be readily understood from thefollowing description, taken in connection with the accompanyingdrawings, in which Figure l is a plan of the base-work of the seed-boxof a seeding-machine of the class specified provided with my improvedseeddischarging device, and Fig. 2 is a vertical section of portions ofthe same upon a larger scale.

In the drawings, A represents the base-plate of the seed-box of acorn-planter; B, the lugs for securing the same to the frame-work of theplanter, O, the encircling rim of the base-plate; D, rim-lugs serving asa means for attaching the shell of the seed-box to the base-plate; E,the disk-like seed-plate fitted to revolve over and in contact with thebaseplate; F, the grain-cells arranged in a circle through theseed-plate near its periphery; G, the center spindle of the seed-plate,through which it receives its motion; H, a bracket projecting radiallyand upward from the periphery of the base-plate; I, a pivot supported insaid bracket; J, a lever fitted to oscillate freely upon said pivot; K,a sphere provided with an axle and journaled in the bifurcated inner endof said lever in such position as to reach the grain-cells in the seedplate, as clearly shown in the drawings; L,an outward prolongation ofthe lever, forming a thumb-piece, and M the dischargepoint in thebase-plate, directly over which the sphere K is located. As theseed-plate revolves each grain-cell in turn is brought over thedischarge and the grain in the cell is at liberty to leave the cell anddrop. The plate revolves freely under the sphere, which drops slightlyinto each grain-cell as the cell reaches the discharge-point and insuresthe discharge of the grain from the cell. The sphere, by reason of itsspherical form, does not in the least tend to alter the form of thegrain-cell by wear, as is the case with all other forms of knockers withwhich I am familiar. The thumb-piece L permits the freedom of motion ofthe lever to'be tested by hand. The lever, instead of being locatedradially with reference to the circle, as shown, may of course bearranged tangentially, as is common with knocking levers for this classof machines, the axis of the sphere being, of course, arranged radially,as shown; but the radial arrangement of the bracket and lever permits amore ready inspection and hand manipulation of the lever than would bethe case with the lever arranged tangentially within the circle of theseed-box.

I claim as my invention- 1. In a seeding-machine, the combination of aseed-plate provided with grain-cells, a pivoted lever, and a sphericalknocker journaled in the end of said lever in position to engage thegrain-cells at their discharge-point, substantially as and for thepurpose specified.

2. In a seeding-machine, the combination of a disk provided with acircle of grain-cells, a pivoted lever arranged radially with referenceto the seed-plate, and a revolving knocker journaled in said lever inposition to engage the graiircells as they arrive at theirdischarging-point, substantially as and for the purpose specified.

3. The combination of a seeding-plate having a circle of graiircells, apivoted lever arranged radially with reference thereto, and a spherejournaled in said lever and arranged to engage the grain-cells as theyreach their discharging-point,substantially as and for the purposespecified.

4. The combination of a seed-plate having grain-cells, and a pivotedlever provided with a revolving knocker arranged in position to engagethe grain-cells at their discharging point, and having a thumb-piece,substantially as and for the purpose specified.
